Yes, but why would they use what we humans call morality? We do for the reasons you cited above, but I don't think they really apply to them. That's why I don't blame them more than I would an animal, or a highly advanced robot who, despite a AI able of reasoning, is not programmed to act "morally".

While a certain amount of selfishness is an evolutionary advantage, an utter lack of selflessness produces the very opposite effect.

Evolution is neither all important nor all powerful. Especially for AB. They're a relatively recent creation, and from the point of view of evolution, they're not even a separate species. (Since they come from humans and youmas, and don't reproduce.)

Evolutionary pressures are pretty mild, and if I were them, I'd worry more about overgrazing than about Claymores.

Spoiler for Manga, vol 12:

Well, that may change with the Organisation's new policy, but that's an even more recent phenomenon.

So, even if cooperative behaviour was better for the "species" as a whole,

Spoiler for Manga, ch 71:

and so far, the most salient example of cooperative behaviour we've seen got about 30 AB slaughtered,
